The sign shown in the picture above represents Scarf sign.
- The elbow cannot be drawn, with gentle traction on the upper extremity, across this term infant’s chest.
- The resting tone of the upper extremities can be assessed by eliciting the scarf sign.
- Gentle traction of the upper extremities across the chest in a rostral direction (“placing a scarf on the infant”) while examining the position of the elbow reveals a decreasing displacement of the elbow as gestational age increases.
